Abstract
Migrating an active VM from a first data center to a second data center having a passive counterpart of the active VM includes freezing the active VM at the first data center, creating an active VM at the second data center that corresponds to the passive counterpart, and restarting the active VM at the second data center. Migrating an active VM from a first data center to a second data center may also include waiting for the passive counterpart to be synchronized with the active VM at the first data center prior to converting the passive counterpart. Creating the active VM at the second data center may include providing a snapshot of a volume containing the passive VM.
